Finding the proteins that unpack DNA

A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions. The method, ...

Missing link found between pathways involved in cell development

A new mechanism that coordinates human development in response to signals from outside the cell has been discovered by researchers at the Wellcome Sanger Institute and the Wellcome - MRC Cambridge Stem Cell Institute. Reported ...

More complex biological systems evolve more freely

Our genes (aka. the genotype) determine our characteristics (aka. the phenotype). Evolution acts on changes in the phenotype, which occur when mutations change the underlying genotype. But what changes to the phenotype can ...

Rethinking transcription factors and gene expression

Transcription—the reading of a segment of DNA into an RNA template for protein synthesis—is fundamental for nearly all cellular processes, including growth, responding to stimuli, and reproduction. Now, Whitehead Institute ...
